Mechanical properties of low alloy steel foams: Dependency on porosity and pore size

On the particle size effect in expanded perlite aluminium syntactic foam

“…There has been good agreement on the effect of density and cell shape on the mechanical properties. It is now well accepted that the plateau stress and energy absorption of the metallic foams depends on density [1,[8][9][10][11][12] and cells geometry [3]. In the case of metallic syntactic foams, the density and cell shape cannot always be varied freely since they depend on the filler particles' morphology and density [13].…”

Pores distribution statistical analysis for metal foams obtained by casting-dissolution process

“…It was found that the relationship between the compressive strength and the porosities is completely linear relation beyond the effect of pore size distributions on the mechanical properties [11]. Furthermore, it is worth noting that both the foam structure and the pore morphology depend on the fabrication method, utilized during manufacturing of the foams, which in turn determine the mechanical properties [12].…”

“…Several authors had shown limited number of methods to produce open cellular structures that allow obtaining uniform pore distribution [12]. In order to probe complex porous structures, high resolution X-ray computed tomography (XCT) or MRI techniques have been used in recent years.…”

“…In order to probe complex porous structures, high resolution X-ray computed tomography (XCT) or MRI techniques have been used in recent years. Bekoz et al [12], calculated the area of each pore on the SEM image and measured the pores size, shape and size distribution using Clemex Vision PE commercial image-analyzer software.…”

Cyclic compression behavior and energy dissipation of aluminum foam–polyurethane interpenetrating phase composites

“…Therefore, the mechanical parameters affecting the performance of AF and PU, respectively, also affect the mechanical behavior and structural stability of AF-PU composites. Different relative densities and pore size are two main factors influencing mechanical behavior of AF [13][14][15][16][17][18][19] and the usual influence parameters on the absorbed mechanical energy of PU are frequency, temperature and vibration amplitude [20][21][22][23][24]. In order to understand what kind of AF-PU materials are the most suitable for applying hysteretic damping devices in seismic resistant buildings, we will investigate the damping capacity of AF-PU composites with different corresponding porosity and pore size under different cycling frequency, vibration amplitude, temperature aging and cycle numbers.…”
